SPECIFICATION forming part of LettersPatent No. 285,170, dated September 18, 1883.

Applieatitn filed May 7, 1883.

(No model.)

I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My present invention relates to certain improvements in gas ranges or stoves; and it consists of a closed combustion-chamber in combination with burners for heating the top portion of thestove.

My invention further consists of a detachable deflector, made'of iron, fire-clay, soapstone, or other suitable material, having a convex form on its under side. Said deflector is placed between the oven and roasting-apartment of the range. The sides of the range are made hollow, thereby admitting air from the bottom of the range through the said sides and into the oombustionvchamber, the latter being provided with a flue which is adapted to connect witha chimney, thereby making a forced blaze, the waste gases from which are conveyed to the said fine and chimney.

In gas-ranges heretofore manufactured the top portion, in which the burners are located, is perforated on the sides and often on the top, thereby allowing unpleasant odors and injurious gases to escape into the room.

.VVith my improved closed comb ustion-ohamber this defect is entirely overcome, all as will be more fully hereinafter set forth.

I11 the accompanying two sheetsof drawings, Figure 1 represents a front view of the range complete. Fig. 2 represents a sideview of the same. Fig. 3 is a vertical section through the range on line 0 0 of Fig. eifshowing the interior construction of the top combustion 'chamher, also the oven, roasting-apartment, together with the arrangement of the detachable deflector and burners.

Fig. 6 represents a view of the bottom of the closed combustion-chamber with top removed, and showing the burners and air-communicating flue, and also the exit-flue. Fig. 7 represents a device for combining the gas and air previous to combustion, and also showing stop-cock and connections, enlarged scale. Fig. 8 represents a partial section of the deflector, oven, roasting-apartment, and flue around the same, and also showing one of the burners in operation, enlarged scale. Fig.

The followingis a more detailed description of my invention and the manner of operating the same.

A represents the range or stove, provided with the oven A, beneath which is the ,roasting-oven A", said ovens having doors A A B represents the top combustion-chamber, having closed sides, and provided with the extension 13, which latter is adapted to con vcy the foul gases to the chimney by means of the flue-pipe I). Said chamber is further provided with a top plate, 0, adaptedto receive griddles or covers 0". (See Fig. 5.)

a represents the airspace between the ovens and outer shell of the stove. Said space com- ,municates with the fresh air at the bottom of 13, and flue by means of the aperture a B represents my improved deflector, hav- Said deflector is adapted to be removable, and is placed be tween the ovens A A before referred to, leaving an air-space, a, between them, as shown, or it can be secured to the bottom of the oven' A. Said deflector rests upon lugs 1' (see Fig. 9) when in use.

The following is the manner of operating my improved gas stove or range: A gas-tube is connected at W to the gas-pipe s, which latter extends upwardly on two opposite sides of the stove, as shown. At 8 are stop-cocks and connections for admit-ting the gas to the burners. 8 represent pipes, into which the mingled gas and air is admitted at 3*, Fig. 7, which, issuing from the open burner or pipe 8, is then ignited, thereby heating the deflector R, which serves both as a radiator and flame-distributer. (See Figs. 3 and 9.) Said deflector is also used for heating the oven A. The air entering into combustion with this flame is admitted below the door A and escapes through openings 0 (see'Fig. 9, 850.) into the space a, leading to the chimney. The form of this deflector is such as to spread out the flame, which in practice completely cov ers its convex surface. Said deflector may be corrugated, as shown in Fig. 8, for the purpose of impinging the flame more effectively therewith. 8 represents similar pipes and connections for heating the top chamber, B. Said pipes terminate in four open burners, s. The oxygen necessary to combine with the burning gas in this chamber 13 is admitted at the bottom of the stove and into the space a, (see arrow. directiom) thence into or through the aperture a of the bottom plate of said chamber, and finally into the flue 1), before referred to.

In Fig. I have combined the chamber B with a supporting-base. The air enters the chamber B throughan opening, V, thence to the burners, and into the flue b.

9 represents a plate or griddle, which can be adapted for broiling or similar culinary purposes.

Having thus described my invention, what I' claim as new, and desire to secure by Letters Patent, is-

1. In a gas stove or range, the'combination of Bunsen or atmospheric burners (in which the gas and air are united before entering the stove) with a combustion-chamber having 0 closed sides and top, and adapted to receive air and waste gases through its bottom side, and said chamber being further provided with an exit-flue for conducting the products of combustion into a suitable pipe or chimney, substantially as shown and described.

2. In a gas stove or range having hollow side walls and provided with the baking-oven A and roasting oven A the combination of the convex deflector R with burners s, intro- 5c duced through the sides and near the top of said roasting-oven A and air-passages 0, substantially as shown and described.

3. The combination, in a gas stove or range, A, provided with hollow sides a, gas-tubes s, 5 5 stop-cocks SJ, tubes 8 s and evens A A, of the removable convex deflector It and closed combustion-chamber B, the latter adapted to connect with the said hollow sides a, and provided with the flue-exit b, the whole arranged and adapted for use substantially as shown and set forth.

In testimony whereof I have affixed my sig nature in presence of two witnesses.
